REFRIGERATOR DRAIN-TRAP.

Specification of Letters Patent.

Patented Oct. 21, 1919.

Application filed December 24, 1918. Serial N 0. 268,174.

To all whom 222 may concern: Be it known that I, JOHN W. KELLER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Refrigerator Drain-Traps, of which the following is a specification.

This invention relates to devices for catching the dripping's from the drain pipe of refrigerators, and its object is'to provide a novel and improved device of this kind which is constructed to form a trap for pre venting the escape of sewer gas into the room, and which can be easily cleaned.

The object stated is attained by means of a combination and arrangement of parts to be hereinafter described and claimed, and in order that the same may be better under stood, reference is had to the accompanying drawing forming a part of this specification.

In the drawing,

Figure 1 is a plan view of the device, and

Figs. 2 and 3 are cross-sections on the lines 2-2 and 33, respectively, of Fig. 1.

Referring specifically to. the drawing 5 denotes a collecting basin or pan adapted to be placed beneath the drain pipe 6 of a refrigerator to catch the drippings from the melting ice and conduct the same to a waste or sewer pipe 7 projecting up through the floor 8 of the room in which the refrigerator is located.

The basin 5 is circular, and off to one side of its center and deepest portion is a bottom outlet nipple 9 to which the waste pipe 7 is connected by a screw or other suitable joint.

In order to prevent the escape of sewer gas from the waste pipe 7, the inlet end thereof is liquid sealed, the basin 5 being constructed to form a trap. This trap is produced by a narrow radial wall 10 spaced a short distance from the wall of the basin and extending from a point at or about the center thereof to its edge. At its longitudinal ends, the wall 10 is continued down to the wall of the basin as shown at 11. The walls 10 and 11 are located above the outlet nipple 9, and they form a conduit 12 leading upwardly thereto from the center or deepest portion of the pan 5. The top or inlet end of the nipple 9 is located at a higher level than the center portion of the pan, and hence it will be seen that when the pan is filled with water up to the level of said end of the nipple as shown in Fig. 2, the water also rises in the conduit 12 and as there is no communication between the pan and the waste pipe 7 except by the Way of this 'condult, it will be evident that a Waterseal is produced which effectually prevents the escape of sewer gas from the waste pipe. The basin 5 and the ,walls forming the conduit 12 are all in one piece, and the.

removed, a few turns suflicing to disconnect it from the waste pipe 7.

The lateral connection of the device with the pipe 7 enables the basin 5 to be swung about the latter in a large circle, so as to adjust itself to receive the discharge from the pipe 6, wherever the latter may be located in the vicinity of the pipe 7.

I claim:

1. A refrigerator drain trap comprising a collecting basin having a depending bottom outlet nipple located off the center of the basin and opening thereinto at a higher level than its deepest portion, and provided with a conduit extending upwardly from said deepest portion of the pan tothe outlet, said conduit being the sole'avenue of communication between outlet and the interior of the pan.

2. A refrigerator drain trap comprising a collecting basin deepest at its center and having a depending bottom outlet nipple off said center and at a higher level than the deepest portion, and a wall in the pan extending in spaced relation therewith radially from the center thereof and above the outlet, and joined to the wall of the pan to form a conduit extending upwardly from the deepest portion of the pan to the outlet, said conduit being the sole avenue of communication between the outlet and the interior of the pan.

In testimony whereof I aflix my signature.

JOHN W. KELLER.
